Some observers pan the move, noting Google's support for Flash rival HTML5.

Google with its Chrome browser is making accommodations for the Adobe Flash Player, a move that did not sit well with some early commentators wondering why Google is now pushing Flash when it has backed HTML5, a potential rival to Flash.

The Flash Player will be included in downloads of Chrome as soon as possible, according to the companies. The initial effort Tuesday involves an integration of Chrome and Flash Player in the developer channel. Additionally, Adobe and Google are part of an effort to improve interaction between browsers and plugins.

"When users download Chrome, they will also receive the latest version of Adobe Flash Player. There will be no need to install Flash Player separately," said Linus Upson, vice president of engineering at Google, in a blog post. Users will automatically receive updates related to Flash Player using the Chrome auto-update mechanism. Also, Google plans to further protect users by extending the Chrome sandbox to Web pages with Flash content.

Some persons posting comments attached to the Google blog post did not take kindly to Google cozying up to Adobe.

"The future of the Web should be standards-based: HTML, CSS, and JavaScript. Not some old clunky proprietary plug-in," said commentator Anders Tornblad

"Ugh. And here I thought we were all getting close(ish) to completely ditching Flash and you guys decide to bundle Flash with Chrome. What the hell happened to open standards," asked another person.

"Shouldn't you be concentrating on enhancing HTML5 rather than meshing the browser with proprietary plug-ins," asked another person commenting.

Others, including a commentator identified as Flash developer Joel Fiser, defended the alliance.

Adobe also is working with Google, Mozilla and others on an API to provide a better way for browsers and plug-ins to interact.

"While the current NPAPI has served the industry well, it lacks the flexibility and power to support the pace of innovation we see ahead. We expect that the new API specification will offer some distinct benefits over the current technology available," Betlem said. The API will be OS- and browser-neutral to minimize the chance of inconsistent behavior across platforms. It also will offer performance benefits and enable tighter integration with host browsers, Betlem said.

Google has participated in the Adobe-led Open Screen Project, which is an effort to provide a Flash-based runtime environment for rich content across different devices.
